Cataract surgery with intraocular lens implantation in 3 brothers with megalocornea: Long-term follow-up

Cataract surgery in patients with megalocornea is challenging because of the large capsular bag in which a conventional intraocular lens (IOL) does not fit and the atrophic nature of the iris. We report the procedures and outcomes of cataract surgery in 6 eyes of 3 brothers with megalocornea. In 2 eyes, a posterior chamber IOL (PC IOL) was inserted and sutured to the iris with 10-0 nylon sutures. In the other 4 eyes, an iris-clip anterior chamber IOL (AC IOL) was inserted. In all cases, the postoperative corrected distance visual acuity (CDVA) was 6/6. In the PC IOL group, 1 IOL dislocated and was replaced with an iris-clip AC IOL. In the AC IOL group, 1 IOL subluxated and was reenclavated. In both eyes with dislocation, the CDVA improved to 6/6.
